returns the numeric value corresponding to the character string
\fIstr\fR in the value space of Feature file field \fIname\fR in the
header pointed to by \fIhd\fR.   If \fIstr\fR is not a possible value
for \fIname\fR then -1 is returned.
If \fIname\fR is not defined as a CODED field in \fIhd\fR then -2 is
returned.

Assume field name \fIzeta\fR was created as a field of type coded with
possible values "ZA", "ZB", and "ZC" in ESPS feature file \fIhd\fR.   
"ZA" corresponds to a value of
0, "ZB" corresponds to a value of 1, and "ZC" corresponds to a value of
